science news 7.11.2019

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.

Structural and biochemical studies clarify the methylation mechanism of anticodon in tRNA
These studies look like nerdy little details to most people, but I do believe that the clues to the origin of life (ie how did RNA begin to make protein) is encoded in there somewhere.

A solution to a hairy problem in forensic science
In an effort to make hair comparison a more useful technique for investigating crimes, scientists at the National Institute of Standards and Technology (NIST) have developed a new way to dissolve hair proteins without destroying them. Once in solution, the protein molecules from two hairs can be analyzed and compared, yielding objective, quantitative results.
